These high quality metal bodies are a new standard in airsoft for quality and price in an M4 metal receiver. MadBull has obtained the licenses to use authentic manufacturer logos, which makes a high quality receiver look even better. This metal body includes the foward assist assembly, locking body pins, a flora pin, trigger guard pin, and the charging handle spring.

We have tested these metal bodies with G&P mechboxes and they fit tightly with no wobble and no gaps between parts. With the difficulties we have experienced with some brands and types of metal bodies, the MadBull receiver is pretty much a drop-in, though you should have experience before attempting to install it.
